The state previously allowed autonomous-car testing on public roads, provided a driver was in the driver’s seat and the car was equipped with a steering wheel, a brake pedal, and an accelerator. Now, California Governor Jerry Brownhas signed a bill that permits testing of cars without drivers or driver controls in specific locations.

Specifically, the tests will be permitted “only at a privately owned business park designated by the [Contra Costa Transportation] authority, inclusive of public roads within the designated business park, and at a GoMentum Station located within the boundaries of the former Concord Naval Weapons Station.”
